During this process, you will:

  • Create a virtual machine
  • Using a virtual machine will decrease the chance of errors and protect your computer from potential viruses. It also makes it easier to start from scratch with a fresh installation of Windows (if you end up needing to). However, it can be done without using a virtual machine (check our document above).
  • Install and set up VX Manager
  • Install and set up Techline Connect
  • Use SPS2 to reprogram your vehicle using the VCX Nano

What you need before starting:

  • A laptop
  • An internet connection
  • An active “Service Programming System (SPS2)” subscription from ACDelco TDS
  • $40 per vin (24 months access)

Important information and tips:

  • Read the guide and watch the video to decide if this is feasible for you. You don’t need to be an expert with computers to successfully do everything but it’s definitely not “plug and play.”
  • Try to follow the instructions as closely as possible. 
  • Do not try to follow the video without reading the step-by-step instructions. The video is just meant to be used as a visual aid.
  • This might take multiple attempts. If you encounter an error, it might be easier to just restart from scratch instead of trying to troubleshoot it.
  • Don’t plug the VCX Nano into your laptop or vehicle until the step says to.
  • The video was created on October 29, 2021. Things may change by the time you use this guide, but it should be similar. The user will try to keep the guide updated and fix errors.
  • This guide specifically addresses the “Service High Voltage Charging System” error with 1st generation Chevy Volts. However, the process should be similar with other vehicles.

The “Service High Voltage Charging System” message is a common problem on first-generation Volts. Often, the only way to fix the error is to reprogram the BECM and HPCM2 modules (even if nothing is inherently wrong with the vehicle). Before you reprogram the modules, you should see if clearing the codes fixes the issue. Also, make sure the battery coolant is not low. If clearing the codes does not permanently fix the problem, you most likely need to reprogram the modules.

  • Before reprogramming, make sure the battery coolant is not low and clear any codes with an OBD2 scanner.
  • He recommends buying a Chevy Volt 2011-2015 SHVCS Defeat Plug ($40) to stop the SHVCS message from triggering again. If you choose to buy it, you can install it before programming your vehicle.
  • He suggests using VMware to create your virtual machine. Others have reported problems when using other virtual machine software.
  • If you don’t live in the United States, you might want to use a VPN and change your location when creating your account with ACDelco TDS. The “Service Programming System (SPS2)” subscription might have better pricing and a longer access time in the USA than where you live.


VXDIAG VCX NANO Techline Connect Setup Procedure:

Step 1: Download Windows 10 Media Creation Tool and VMware Workstation (00:00)

  • Search the web to find the download links or click the links below
  • Edit: It might be better to use VMware Workstation 16 Player instead of VMware Workstation Pro. If you use the pro version, your access will end after your free 30-day evaluation. However, you can still use the pro version if you would like. The setup process is similar with both versions.

Step 3: Set up VMware (01:57)

  • Click on the VMware Workstation installation file you downloaded in step 1 to start the installation

Step 4: Set up a virtual machine using VMware (02:58)

  • Start the VMware Workstation program
  • Select “I want to try VMware Workstation 16 for 30 days” and continue
  • Select “Create a New Virtual Machine” and continue
  • For the “Installer disc image file,” click browse and then select the Windows 10 ISO you downloaded in step 2 and continue
  • Uncheck the box that says “Power this virtual machine after creation” and continue
  • Click “Edit virtual machine settings”
  • Change the “Number of cores per processor” and “Memory.” This will make the virtual machine run smoother. The values you select depend on the specification of the laptop you’re using.
  • I suggest setting the memory to half of what your laptop contains and setting the “number of cores per processor” equal to the number of cores your CPU has.
  • My laptop has 16 GB of memory/RAM and a 6 core CPU. Therefore, I selected 8 GB of memory and 6 for the “number of cores per processor.”

Step 5: Power on the virtual machine and set up Windows (04:26)

  • Select “Power on this virtual machine”
  • As soon as the screen says “Press any key to boot from CD or DVD,” click the center of the screen and press any key. If you don’t do this fast enough, you’ll have to close the window and try again.
  • When the screen says “Activate Windows”
  • Select “I don’t have a product key” and continue
  • When the screen says “Select the operating system you want to install”
  • Select “Windows 10 Pro” and continue
  • When the screen says “Which type of installation do you want?”
  • Select “Custom: Install Windows only (advanced)” and continue
  • When the screen says “How would you like to set up?”
  • Select “Set up for personal use” and continue
  • When the screen says “Let’s add your account”
  • Select “Offline account” and continue
  • When the screen says “Sign in to enjoy the full range of Microsoft apps and services”
  • Select “Limited experience” and continue
  • When the screen says “Choose privacy settings for your device”
  • Turn off everything and continue
  • When the screen says “Let Cortana help you get things done”
  • Select “Not now” and continue

Step 6: Configure display settings (optional) (07:31)

  • Go to system settings and find the display settings.
  • Do this if you need to change the resolution or make text larger

Step 7: Log in to ACDelco TDS and download Techline Connect (08:18)

  • You need to have an active “Service Programming System (SPS2)” subscription from ACDelco TDS before attempting this step
  • Log in to ACDelco TDS
  • Click on your vehicle programming subscription and then click “Add VIN.” It will open a new webpage.
  • My subscription already shows the VIN of my car because I’ve done this before. You don’t enter the VIN until step 11 or 12.
  • Click “Download Techline Connect”

Step 8: Download and install VX Manager (09:43)

  • Go to the VXDiag website and find the download page (or type in the link below)
  • Edit: People are reporting problems with the latest version of VX Manager. However, the 1.8.4 version appears to still work. If you have this problem, the link below includes the download for the 1.8.4 version.
  • Click the VX Manager Mega Link
  • From the Mega webpage, click download
  • The download might be flagged as dangerous or a virus. Bypass the warnings (see video) and open the file. Install the program.
  • This is safe to do because you are using a virtual machine
  • When the screen says “Select Components”
  • Select “GM – GDS/Tech2Win” and continue
  • Before clicking finish, plug your VCX Nano into your laptop
  • When the screen says “New USB Device Detected”
  • Select “Connect to a virtual machine,” click the virtual machine from the list, and continue
  • Click finish

Step 9: Set up VX Manager (12:52)

  • Click “Firmware,” toggle update, and click “Upgrade.” Close the pop-up window when it finishes.
  • Click “Update License” and wait for it to finish.
  • Click “Diagnostic” and then “PASSTHRU.” Click Install. When it finishes, close the window and close VX Manager.

Step 11: Prepare for vehicle programming (18:36)

  • Clear the codes, if any, from your vehicle using an OBD2 scanner. I think you can do this with the software as well but I didn’t try.
  • Unplug the charger from the car
  • Your laptop should have a full charge before programming. However, I suggest leaving it connected to the charger, if possible.
  • Put the vehicle into accessory mode
  • 1st generation Chevy Volt: hold the power button for 10 seconds without pressing the brake
  • Turn off the radio, interior lights, etc. You do not want the 12V battery to drain more than necessary.
  • Plug the VCX Nano into the vehicle’s OBD2 port
  • Click “Connect Vehicle”
  • When the screen says “Please select a device type:”
  • Select “VXDIAG” and continue
  • Click SPS2
  • At some point, you’ll get a pop-up that asks if you want to use the car’s VIN with your subscription slot. I think it comes up after you click “next” in Step 12 (around the 20:00 mark in the video). I already did this before I made the guide so the video doesn’t show it.

Step 12: Reprogram the Battery Energy Control Module (19:59)

  • I did not fully complete this step in the video because I already reprogrammed my vehicle
  • Click “Next”
  • Select “Battery Energy Control Module” and click next
  • Continue to click next until the software begins to reprogram the vehicle. Don’t do anything until it completely finishes. It might take a while. The vehicle’s instrument cluster will display warning lights during the process (this is normal).
  • If your module is already up-to-date, you might get a warning about reinstalling the same calibration. It’s okay to do this. You still need to reprogram it even if it’s up-to-date.
  • After it is finished, continue to step 13

Step 13: Reprogram the Hybrid Powertrain Control Module 2 (21:27)

  • I did not fully complete this step in the video because I already reprogrammed my vehicle
  • Repeat step 12 but select “Hybrid Powertrain Control Module 2” instead
  • After the “Hybrid Powertrain Control Module 2” is finished reprogramming, close the program
  • Turn off the car and turn it back on normally. You are finished.
